What do Audi 30, 35, 40, 45 mean?

[SanCole]

Audi's 30, 35, 40, and 45 represent the horsepower of the engine. The larger the number, the greater the horsepower of the engine and the better the performance. Here is some additional information: 1. Audi: Audi is a luxury car brand under Audi AG, a subsidiary of the Volkswagen Group in Germany. As a representative of high technical standards, quality, innovation capabilities, and classic car models, Audi is one of the leading automotive brands. The company is headquartered in Ingolstadt, Germany, and has subsidiaries in many countries, including China. 2. TFSI: The TFSI suffix, such as 45TFSI or 35TFSI. The "T" stands for turbocharging, the "F" stands for stratified combustion, and the "SI" stands for direct fuel injection. TFSI refers to a direct fuel injection engine with turbocharging and stratified combustion technology, which is a patented technology of Audi.

This is essentially a performance tier designation Audi uses across its model range, not an exact displacement figure. The numbers are calculated based on factors like engine power and torque - for instance, 30 typically corresponds to around 130 horsepower, 35 might indicate 150hp, 40 reaches up to 190hp, while 45 represents 245hp or more, delivering noticeably stronger acceleration. The calculation follows Audi's official formula. Having driven the A4 40 variant, I found its power delivery significantly more robust than the 35 version, making highway overtakes effortless and urban acceleration more responsive. For precise horsepower figures, consult Audi sales staff or official model specifications when purchasing. This labeling system proves practical for quickly gauging a vehicle's performance potential. Audi has extended this nomenclature to its electric e-tron series, ensuring familiarity for existing customers. Note that the same designation (e.g., Q5 45) may indicate slightly different outputs across models, but overall this system serves as an excellent tool for matching cars to driving needs.

I have to say, Audi's numbering system is like giving cars a grade—simple and easy to understand. The numbers 30, 35, 40, and 45 mainly indicate the horsepower level of the car, with higher numbers representing greater horsepower and better performance. For example, 30 is the base tier, suitable for daily commuting; 35 is slightly better, offering a comfortable commute; 40 has more power, making highway overtaking smoother; and 45 packs a punch with quick acceleration, ideal for those who love driving fast. When I was buying a car, I found these labels much simpler to remember than engine displacement—the 35, for instance, has around 150 horsepower, which is effortless for city driving, while the 40 is great for both daily use and weekend getaways. I recommend test-driving the A4 in both 35 and 40 variants to feel the actual difference. Audi uses this system to make it easier for us to choose a car, so don’t worry about adjustments for lower-numbered new energy vehicles. Overall, just remember that it represents a sense of tiered performance, and that’s all you need.

In my opinion, Audi's 30, 35, 40, and 45 are essentially codes representing engine performance levels. A 35 might indicate around 150 horsepower, while a 40 approaches 200 horsepower. Larger numbers signify higher horsepower for a more exhilarating drive – for instance, an A4 40 accelerates a few seconds faster than a 35. But don't be fooled by these seemingly cryptic codes; they're fundamentally Audi's way of making model differentiation transparent. Personally, I find the 40 variant perfectly balanced for both city commutes and highway driving. Paying attention to these codes when car shopping can help you effortlessly identify the model that best suits your needs.
